Audio is crackling... speakers, headphones... doesn't matter. Is it only in my case?

@c4pp4
No, same for me.

@c4pp4 Thank you for the reply!
The anbox-ubuntu-touch package was available all of a sudden a week or so ago. Got everything installed and running.
Perhaps this was all related to the OTA updates.

I think I got something. I've tried some audio files with sampling frequency 48kHz and the output was clear. If you don't have some you can convert any via ffmpeg:

ffmpeg -i "original.mp3" -ar 48000 "new.mp3"

Maybe it has something to do with rate=48000 in /etc/pulse/touch.pa file:

.ifexists module-droid-card-24.so
load-module module-droid-card-24 rate=48000 quirks=+unload_call_exit
.endif

I'm not sure how to change the rate and test it. Maybe @fredldotme could help.

fredldotme

@c4pp4 nice catch!

What you can do to test small modifications to the Halium portion (where this file is from):

Reboot into recovery
Connect to the device via ADB
Mount the Halium system image: mount /system/var/lib/lxc/android/system.img /tmp
Edit the Halium override file to your liking: nano /tmp/halium/etc/pulse/touch.pa
Unmount the Halium image again: umount /tmp

I'd say you can then go ahead and make a pull request on GitHub with your changes if you manage to find a fix for your issues.

@fredldotme
Thank you. Unfortunately changing touch.pa has no effect on quality.

@fredldotme
/etc/pulse/daemon.conf

default-sample-rate = 44100
alternate-sample-rate = 48000

/etc/pulse/touch.pa

.ifexists module-droid-card-24.so
load-module module-droid-card-24 rate=44100 quirks=+unload_call_exit
.endif

syslog

May 15 03:06:10 ubuntu-phablet pulseaudio[6939]: [pulseaudio] droid-util.c: Requested sample rate 44100 but got 48000 instead.
May 15 03:06:10 ubuntu-phablet pulseaudio[6939]: [pulseaudio] sink.c: Default and alternate sample rates are the same.

It always falls to 48kHz. It's weird.

@c4pp4 It is strange though, that there is no documented way of getting the ubports version of android to use rootfs-overlay, just as the snap version does. Indeed, repacking the squshfs isn't such a big deal (although I wouldn't have known of the parameters you used, but still, just dropping a file into the overlay directory tree would make things so much easier!
BTW, the sound that you get from android apps after completing this step is quite choppy, not really suitable for real use, more a proof of concept.

Mount the Halium system image: mount /system/var/lib/lxc/android/system.img /tmp

There is no directory /system/var/lib in recovery mode, I also cannot find a system.img anywhere. Has this changed recently?

Edit the Halium override file to your liking: nano /tmp/halium/etc/pulse/touch.pa

Wouldn't this be the file /system/halium/etc/pulse/touch.pa?

EDIT: losetup -a says that /dev/loop0 is pointing to /halium-system/var/lib/lxc/android/system.img, yet there is no directory /halium-system. How can I access it?

@fredldotme thank you so much for your awesome work. I just flashed the port a few days ago and everything is working super smooth.

I followed during the installation process your instructions and of @christophe14 (post 160). It helped me a lot.

The ubports installer caused a lot of trouble during the installation. I got a lot of error messages (they are already on github). The biggest problem for me was for some reason to boot into fastboot mode. It took me easily 40 attempts. Don't know why. For some reason the ubports installer also did not recognised the device (all the necessary drivers were installed. Switched over to the installer on fedora and did not had any problems.

Keep up the great work. I am amzed by this wonderful community and what you all have already achieved.

@jro
What is the output of

adb shell ls

when the device is connected in recovery mode?

c4pp4

Some audio tweak:

boot device into recovery
mount system.img:

adb shell mount /system/var/lib/lxc/android/system.img /tmp

when playing 44.1 kHz audio stream the sound is crackling, default sample rate is 48 kHz and I think the resampler is too slow, fix it using higher latency via deep buffer flag:

adb pull /tmp/etc/audio_policy.conf
sed -i '/AUDIO_OUTPUT_FLAG_PRIMARY/{s/FAST/DEEP_BUFFER/}' audio_policy.conf
adb push audio_policy.conf /tmp/etc

ringtone volume is too low, it's played via output-speaker+wired_headphone port, set appropriate acdb_id:

adb pull /tmp/etc/audio_platform_info.xml
sed -i '/Custom mapping starts here/a \        <device name="SND_DEVICE_OUT_SPEAKER_AND_HEADPHONES" acdb_id="799"/>' audio_platform_info.xml
adb push audio_platform_info.xml /tmp/etc

sound is distorted when max volume is used, correct max volume:

adb pull /tmp/etc/mixer_paths.xml
sed -i -e '/RX7 Digital Volume/{s/92/86/}' -e '/RX8 Digital Volume/{s/92/86/}' mixer_paths.xml
adb push mixer_paths.xml /tmp/etc

umount system.img:

adb shell umount /tmp

reboot the device

@c4pp4 Wonderful, aber you able to integrate this permanently into the system image with a PR on Github? Your solution is too complex to apply and also will be overwritten by an update

fredldotme

Yeah, those changes presented as a PR would be highly appreciated! I'm currently occupied with a lot of other things, so I probably can't do it myself in the short term. The files you're modifying are probably in the suzu and loire repos on GitHub linked in the top post.

fredldotme

Thanks again to @c4pp4 for preparing those changes as a pull request, the changes will land within the next two days.

c4pp4

@fredldotme
No problem

I'm trying to achieve 44.1 kHz as the default rate or find out why is resampler too slow. I'm not sure if it's pulseaudio server, droid module or qcom driver related or something else.

c4pp4

@fredldotme
I think I find out why it's always using 48 kHz. It's related to qcom/audio/hal. According to this commit https://github.com/fredldotme/device-sony-common/commit/b3235f337a371d7746fe591e3adcaca99c90dc4f we are using qcom/audio/default/hal/audio_hw.c where adev_open_output_stream function is always assigning 48 kHz rate regardless of what we configure in audio_policy.conf/touch.pa:

3065       out->sample_rate = out->config.rate

newer version contains:

5295       if (config->sample_rate == 0) {
5296                   out->sample_rate = out->config.rate;
5297               } else {
5298                   out->sample_rate = config->sample_rate;
5299       }

Is there a chance to test patched version?
